UNITED STATES PATENT OFFICE FRANK RI-IIND, OF MERIDEN, CONNECTICUT, ASSIGNOR OF THREE-FOURTIIS TO CHARLES S. UPTON, OF NEIV YORK, N. Y.

WlCK-RAISER FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 440,608, dated November 11, 1890.

Application filed August 12, 1889.

To all whom it may concern:

Be it known that I, FRANK RHIND, a citizen of the United States, and a resident of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Wick-Raisers for Central-DraftLamps, of which the following is a specification.

This invention is an improvement in wickxo adjusters for central-draft lamps, or that class of lamps in which the tube for supplying air to the inner mantle of the flame passes through the reservoir of the lamp, and is fully disclosed in the following specification, of which the I 5 accompanying drawings form a part and in which similar letters of reference indicate like or equivalent parts wherever found throughout the several views.

Figure 1 is a central vertical section of a central-draft lamp provided with my improvement, the burner being removed. Fig. 2 shows a modified form of the improvement, the lamp-reservoir and central tube being also in central vertical section; and Fig. is

an elevation of one of the wick-holders employed by me.

Referring to Fig. 1, A represents the reservoir and B the central tube of a central-draft lamp. C indicates the wi.ckholder, and C the wick.

In this form of construction the wick-holder tube C is of such diameter as to fit over and to slide upon the central tube B. Hinged at or near the bottom of the wick-holder tube C,

- 3 5 on opposite sides thereof, are clamps or jaws G. These clamps are preferably of the form shown in Fig. 3, and are provided at their tops with a plate G, having serrated teeth, which when the clamps are in position press upon the wick and hold it firmly in contact with the wick-holder C. Attached to the plate G, on the outer side thereof, are springs g, which when the wiclcholder and adj ustertube are in position press upon rods or braces 4 5 E within the reservoir of the lamp and which are firmly attached to the walls thereof. Connected with the wick-holding tube C is a rod or bar H, which passes up through the top of the reservoir through a slot communicating with the neck of the lamp, and is curved outwardly and downwardly and passes through Serial No. 320,496. (No model.)

a tube K, fixed in the lamp, as shown in Figs. 1 and 2. This construction is similar to that of many central-draft lamps now in use and forms no partof the invention claimed herein. 5 5

I prefer to employ two of the rods or braces E, and to arrange them as shown in Fig. 1 that is, on opposite sides of the central tube of the lamp and in line with the wick-adjusting rod orbar 1-1. These features, however, are immaterial, as any number of the same may be employed, and, of course, the number of said rods or bracesE will depend upon the number of the clamps or jaws G that are employed. In this form of lamp the burner is removable, o 5 and after the burner has been removed the wick adjuster and holder may be readilylifted from the lamp, at which time the clamps G may easily be released from the wick and the wick adjusted or removed and a new one inserted, as may be desired. When this has been done, the wick holder and adjuster, together with the wick, may be again readily inserted within the lamp by slipping the same over the top of the central tube, the springs 9 coming in contact with the rods or braces E and forcing the clamp in contact with the wick.

In Fig. 2 the rods or braces E are omitted. The wick-holder tube C is placed outside of the wick, or, rather, the wick is placed inside of the holder, the said holder being large enough to admit of this arrangement, and the wick is placed between the holder and the central tube of the lamp. The clamps or 8 5 jaws G in this case are hinged as before, but are curved inwardly and upwardly, and pass between the wick and the central draft-tube and press upon the wick from the inner side thereof, holding the same firmly in contact with the wick-holder C. The operation in this case is the same as with the construction shown in Fig. 1. \Vhen the wick-holder and adjuster-tube are removed, the clamps or jaws G will be readily released from contact 95 with the wick, which may then be readily adjusted or removed and a new one inserted, the same as before described. In this form of construction the springs g come in contact with the central tube of the lamp, which serves in this case the same purpose as the rods or braces E in Fig. 1. It is possible that the springs 9 may be omitted in each form of construction, in which case the rods or braces E (shown in Fig. 1) should be arranged so that they would come in direct contact with the clamps G G, and in Fig. 2 with the outer wall of the central tube B, the wick-holder 0 being of such diameter as to admit of this operation. It is evident that springs 9 may be formed integral with the clamps G and many other changes made in the details of this portion of the construction without departing from the spirit of the invention, the object being only to provide some practical means whereby the hinged clamps or jaws will be pressed against the wick and hold the same in place and facilitate its adjustment when the wick-holder is in position independent of the wick-adjusting bar, which extends above the top of the fount and independent of the upper outer tube, which forms the outer wall of the Wick-chamber in Argand lamps. It will be seen, therefore, that the rods or braces E in Fig. 1 serve the same purpose as the central tube of the lamp in Fig. 2, each constituting simply a friction or bearing surface, by which the clamps or jaws G are brought in contact with the wick, whereby the same is firmly pressed upon the Wick-holder tube 0. \Vith this construction the wick is held firmly in contact with the wick-holder tube 0. There is no possible danger of its becoming misplaced, and it may be adjusted with the greatest nicety by simply raising or lowering the bar H, which may be done from either above or below the lamp.

Having 'fully described my invention, its construction and operation, I claim and desire to secure by Letters Patent of the United States the following:

1. The combination, with the central tube of acentral-draft lamp, of awick-holder moving with the wick, consisting of a band surrounding the central tube, clamps or jaws for holding the wick in contact with said holder and hinged thereto, and bearing-surfaces within the reservoir of the lamp for bringing the clamps or jaws in contact with the wick independent of the means by which the wick is raised or lowered and independent of the outer tube which forms a portion of the wickchamber in Argand lamps, substantially as shown and described.

2. The combination, with the central tube of a central-draft lamp, of the wick-holder movable with the wick, surrounding said tube and adjustable thereon, clamps or jaws for holding the wick in contact with the holder hinged thereto, bearing-surfaces within the reservoir of the lamp, and attachments on said clamps or jaws which contact with said bearing-surfaces, substantially as shown and described.

3. The combination, with the central tube of a central-draft lamp, of a wick-holder surrounding said tube, clamps or jaws hinged thereto for holding the wick in contact therewith, and rods within the reservoir of the lamp, by which the clamps or jaws are held in contact with the wick, substantially as shown and described.

4. The combination, with the central tube of a central-draft lamp, of a wick-holdersurrounded and movable upon said tube, clamps or jaws G G, provided with springs g, hinged to said holder, and rods or braces E, substantially as shown and described.

Signed at the city of New York, in the county of New York and State of New York, this 10th day of August, A. D. 1889.

FRANK RHIND.
